=head1 COMMANDS
=over 4
=item -i, --install
Installs the modules. This is a default behavior and this is just a
compatibility option to make it work like L<cpan> or L<cpanp>.
=item --self-upgrade
Upgrades itself. It's just an alias for:
cpanm App::cpanminus
=item --info
Displays the distribution information in
C<AUTHOR/Dist-Name-ver.tar.gz> format in the standard out.
=item --installdeps
Installs the dependencies of the target distribution but won't build
itself. Handy if you want to try the application from a version
controlled repository such as git.
cpanm --installdeps .
=item --look
Download and unpack the distribution and then open the directory with
your shell. Handy to poke around the source code or do manual
testing.
=item -h, --help
Displays the help message.
=item -V, --version
Displays the version number.
=back
=head1 OPTIONS
You can specify the default options in C<PERL_CPANM_OPT> environment variable.
=over 4
=item -f, --force
Force install modules even when testing failed.
=item -n, --notest
Skip the testing of modules. Use this only when you just want to save
time for installing hundreds of distributions to the same perl and
architecture you've already tested to make sure it builds fine.
Defaults to false, and you can say C<--no-notest> to override when it
is set in the default options in C<PERL_CPANM_OPT>.
=item -S, --sudo
Switch to the root user with C<sudo> when installing modules. Use this
if you want to install modules to the system perl include path.
Defaults to false, and you can say C<--no-sudo> to override when it is
set in the default options in C<PERL_CPANM_OPT>.
=item -v, --verbose
Makes the output verbose. It also enables the interactive
configuration. (See --interactive)
=item -q, --quiet
Makes the output even more quiet than the default. It doesn't print
anything to the STDERR.
=item -l, --local-lib
Sets the L<local::lib> compatible path to install modules to. You
don't need to set this if you already configure the shell environment
variables using L<local::lib>, but this can be used to override that
as well.
=item -L, --local-lib-contained
Same with C<--local-lib> but when examining the dependencies, it
assumes no non-core modules are installed on the system. It's handy if
you want to bundle application dependencies in one directory so you
can distribute to other machines.
For instance,
cpanm -L extlib Plack
would install Plack and all of its non-core dependencies into the
directory C<extlib>, which can be loaded from your application with:
use local::lib '/path/to/extlib';
=item --mirror
Specifies the base URL for the CPAN mirror to use, such as
C<http://cpan.cpantesters.org/> (you can omit the trailing slash). You
can specify multiple mirror URLs by repeating the command line option.
Defaults to C<http://search.cpan.org/CPAN> which is a geo location
aware redirector.
=item --mirror-only
Download the mirror's 02packages.details.txt.gz index file instead of
querying the CPAN Meta DB.
Select this option if you are using a local mirror of CPAN, such as
minicpan when you're offline, or your own CPAN index (a.k.a darkpan).
B<Tip:> It might be useful if you name these mirror options with your
shell aliases, like:
alias minicpanm='cpanm --mirror ~/minicpan --mirror-only'
alias darkpan='cpanm --mirror http://mycompany.example.com/DPAN --mirror-only'
=item --prompt
Prompts when a test fails so that you can skip, force install, retry
or look in the shell to see what's going wrong. It also prompts when
one of the dependency failed if you want to proceed the installation.
Defaults to false, and you can say C<--no-prompt> to override if it's
set in the default options in C<PERL_CPANM_OPT>.
=item --reinstall
cpanm, when given a module name in the command line (i.e. C<cpanm
Plack>), checks the locally installed version first and skips if it is
already installed. This option makes it skip the check, so:
cpanm --reinstall Plack
would reinstall L<Plack> even if your locally installed version is
latest, or even newer (which would happen if you install a developer
release from version control repositories).
Defaults to false.
=item --interactive
Makes the configuration (such as C<Makefile.PL> and C<Build.PL>)
interactive, so you can answer questions in the distribution that
requires custom configuration or Task:: distributions.
Defaults to false, and you can say C<--no-interactive> to override
when it's set in the default options in C<PERL_CPANM_OPT>.
=item --scandeps
Scans the depencencies of given modules and output the tree in a text
format. (See C<--format> below for more options)
Because this command doesn't actually install any distributions, it
will be useful that by typing:
cpanm --scandeps Catalyst::Runtime
you can make sure what modules will be installed.
This command takes into account which modules you already have
installed in your system. If you want to see what modules will be
installed against a vanilla perl installation, you might want to
combine it with C<-L> option.
=item --format
Determines what format to display the scanned dependency
tree. Available options are C<tree>, C<json>, C<yaml> and C<dists>.
=over 8
=item tree
Displays the tree in a plain text format. This is the default value.
=item json, yaml
Outputs the tree in a JSON or YAML format. L<JSON> and L<YAML> modules
need to be installed respectively. The output tree is represented as a
recursive tuple of:
[ distribution, dependencies ]
and the container is an array containing the root elements. Note that
there may be multiple root nodes, since you can give multiple modules
to the C<--scandeps> command.
=item dists
C<dists> is a special output format, where it prints the distribution
filename in the I<depth first order> after the dependency resolution,
like:
GAAS/MIME-Base64-3.13.tar.gz
GAAS/URI-1.58.tar.gz
PETDANCE/HTML-Tagset-3.20.tar.gz
GAAS/HTML-Parser-3.68.tar.gz
GAAS/libwww-perl-5.837.tar.gz
which means you can install these distributions in this order without
extra dependencies. When combined with C<-L> option, it will be useful
to replay installations on other machines.
=back
=item --save-dists
Specifies the optional directory path to copy downloaded tarballs in
the CPAN mirror compatible directory structure
i.e. I<authors/id/A/AU/AUTHORS/Foo-Bar-version.tar.gz>
=item --uninst-shadows
Uninstalls the shadow files of the distribution that you're
installing. This eliminates the confusion if you're trying to install
core (dual-life) modules from CPAN against perl 5.10 or older, or
modules that used to be XS-based but switched to pure perl at some
version.
If you run cpanm as root and use C<INSTALL_BASE> or equivalent to
specify custom installation path, you SHOULD disable this option so
you won't accidentally uninstall dual-life modules from the core
include path.
Defaults to true if your perl version is smaller than 5.12, and you
can disable that with C<--no-uninst-shadows>.
B<NOTE>: Since version 1.3000 this flag is turned off by default for
perl newer than 5.12, since with 5.12 @INC contains site_perl directory
I<before> the perl core library path, and uninstalling shadows is not
necessary anymore and does more harm by deleting files from the core
library path.
=item --auto-cleanup
Specifies the number of days in whcih cpanm's work directories
expire. Defaults to 7, which means old work directories will be
cleaned up in one week.
You can set the value to C<0> to make cpan never cleanup those
directories.
=item --man-pages
Generates man pages for executables (man1) and libraries (man3).
Defaults to false (no man pages generated) if
C<-L|--local-lib-contained> option is supplied. Otherwise, defaults to
true, and you can disable it with C<--no-man-pages>.
=item --lwp
Uses L<LWP> module to download stuff over HTTP. Defaults to true, and
you can say C<--no-lwp> to disable using LWP, when you want to upgrade
LWP from CPAN on some broken perl systems.
=item --wget
Uses GNU Wget (if available) to download stuff. Defaults to true, and
you can say C<--no-wget> to disable using Wget (versions of Wget older
than 1.9 don't support the C<--retry-connrefused> option used by cpanm).
=item --curl
Uses cURL (if available) to download stuff. Defaults to true, and
you can say C<--no-curl> to disable using cURL.
Normally with C<--lwp>, C<--wget> and C<--curl> options set to true
(which is the default) cpanm tries L<LWP>, Wget, cURL and L<HTTP::Tiny>
(in that order) and uses the first one available.
